I agree regarding the e-series. I drove a lot of Ford vans over the years and now driving a MB Sprinter 144 I am still amazed at how well the Sprinter drives. Super smooth, handles well, decent acceleration for an RV, and on long drives I find it super comfortable. Ford vans always drove poorly IMO; maybe with the SMB suspension and mods its better but I love my Sprinter. That being said I wonder how they compare off road... the SMB e-series vans from what I have seen have been to tougher off road places than someone would take a Sprinter? However, for my purposed in the North East a Sprinter based RV is awesome.
